50k records is nothing. Just sort it entirely in memory outside of the database and blast in the results via just plain inserts in the two tables in sorted order so sqlite will always perform a table append and not have to shuffle the pages around. It will be significantly faster if you handle the conflicts yourself in your code in memory using STL or a conventional data structure than using a general purpose database such as SQLite. ____________________________________________________________________________________ Never miss an email again!
